Hi Andy, it looks like a good way to pass an hour if you have nothing better to do. You never know what you may find.
I remember a story my father told me years ago. He served in India and Burma right at the end WWII. When his ship docked on coming home a rumour started going around that they were all going to be searched as they disembarked. This resulted in hundreds of Japanese swords, weapons and other artefacts being dumped over the the side of the ship. A veritable treasure trove if you found the spot, he never told me where
As an aside I once asked him what he did in the war but he said he was to late for the action as it was all winding down when he got there. Apparently his duties consisted of shooting rabid dogs and blowing open safes that had been damaged as the Japanese pulled out. As we never had a visit from the old bill he either never used his skills in civilian life or he was lucky and never got caught, in which case there is hidden stash somewhere he never told us about
